Precisionist
Thank you for purchasing your new Bulova timepiece. Since 1875, Bulova has been committed to providing the right quality and style for a rapidly changing world, delivering exceptional design enhanced by superior technology. Your new Bulova has been precision-engineered and crafted of the finest materials. The following pages provide instructions on how to set and care for your new watch to ensure years of trouble-free timekeeping.
FEATURES
- Exclusive Three Prong Torsional Resonator gives accuracy within 5 seconds/month.
- Chronograph feature with 1/20 seconds, seconds, and minutes time up to one hour.
- Chrono secondhand jumps in 1/8 second intervals (8 times per second).
- Hour minutes and petite seconds time display. Secondhand jumps in ½ second intervals (two times per second).
- Date display.
SETTING THE TIME
- Pull the setting crown out to position “2” (See diagram). If the crown has a “screw-down” lock, then unscrew the crown lock first by turning the crown towards you, then pull it to position “2”.
- Turn the crown to move hands move clockwise until the date changes at approximately midnight.
- Continue moving the hour and minute hands to the correct time. If it is after noon, turn the hands past 12 o’clock again (noon) to set the correct time.
- When the correct time is set, push the crown back to the “NORMAL” wearing position.
SETTING THE DATE
- Pull the crown to position “1” (See previous diagram). The watch will continue to run. Turn the crown away from you to advance to the current date.
- Once the correct date is set, push the crown back to the “NORMAL” wearing position.
NOTE: Do Not set the date as above between the hours of 9:00 PM and 1:00 AM. This may cause the date to be incorrect and the date will have to be reset later.
CHRONOGRAPH (CHRONO) ADJUSTMENT
This MUST be done BEFORE using the Chrono the first time. It does not need to
be repeated unless the watch receives an impact sufficient to move the hand
out of position, or if the battery has been changed.
NOTE: When using the buttons for these adjustments, each button push will
move the hand one step – BUT holding the button down will advance the hand
rapidly.
- Pull the crown out to position “2”.
- If the Chrono second hand is not positioned at the “0” or 12 o’clock position, push button “A” firmly to adjust the hand correctly.
- If the 1/10 second hand (small dial at 2 o’clock) is not positioned at the “0” or 12 o’clock position, push button “B” firmly to adjust the hand correctly.
- Push the crown back to the “NORMAL” wearing position.
USING THE CHRONOGRAPH (CHRONO)
NOTE: The maximum Chrono reading is 60 minutes.
- Push Button “A” to start the chronograph. Push button “A” again to stop the Chronograph.
- Push button “B” to return the chronograph to the “Zero” or starting point.
- The Chronograph can be stopped and started again. Push Button “A”, repeatedly, to “ADD” times together, up to 60 minutes.
HOW TO USE THE TACHYMETER (ON SOME MODELS)
The Chrono second hand only is used for this function.
Step 1. Push and release button “A”, precisely at the start of a measured
kilometer (mile).
Step 2. At the end of the measured kilometer (mile), push and release
button “A” again
Step 3. The Hand position, on the numbered scale at the dial perimeter,
indicates your speed in kilometers (miles) per hour.
Step 4. Reset by pushing and releasing button “B“.
HOW TO USE THE ELAPSED TIME INDICATOR
If your watch is equipped with a rotatable outer dial with one-minute
graduations, this can be used in various ways to check the elapsed time. For
example, if a diver has a 30-minute air supply, he can set the outer ring so
that the triangle is
in line with the minute hand when he submerges. The minute hand will then
indicate on the outer ring the length of time that the diver has been
underwater.
SCREW-DOWN CROWN
If your watch includes a screw-down crown, you have additional assurance that
it will remain watertight. To make the crown operational, it must be turned
toward you until the threads are disengaged. Then, instructions for setting
must be followed. To reseal the crown, press in until the threads engage. Turn
away from you until tight.
LOCKING PUSH BUTTONS (ON SOME MODELS)
When the watch is submerged, this feature allows you to lock the push buttons
for the chronograph so that they cannot be pushed accidentally. To lock the
buttons, simply turn the outer collar of the button clockwise until it is
fully seated against the button recess in the case. Then, test the button to
ensure it cannot be pushed in. Reverse the process when needed.
ABOUT THE POWER CELL
Your new Quartz Watch has a fresh power cell designed to provide maximum
reliability for approximately a year under normal use. If the cell is not
replaced before it is exhausted, the watch will simply stop. The mechanism
should not be harmed in any manner. However, when the power cell becomes
exhausted, it should be removed at your earliest convenience to diminish the
possibility of leakage. Never store your watch with an exhausted power cell in
it. The watch should be brought to an authorized Bulova dealer for replacement
of the power cell. For best performance, the proper power cell should be used.
Note: When the crown is in the “OUT” position, the motor and hands stop.
Only the quartz crystal continues to vibrate, using very little power. If the
watch is to be stored for a length of time, it is recommended that the crown
be left in the “OUT” position to prolong battery life. This does not apply to
models with two hands only.
WATER RESISTANCE
Watch models marked only “Water Resistant” on the case back, without
additional depth markings are not to be used for swimming. For swimming,
models that have the additional marking of “50m,” “100m” or “200m” are
recommended.
300 METER WATER RESISTANCE (MARKED 300m)
This product is recommended for recreational use only. The depth in meters
shown on the watch does not indicate the diving depth of the watch but
indicates the air pressure used in the water resistance testing of the product
in accordance with industry standards.
